Dear fellas, had problem with my Browning o/u last time at skeet, under barrel was light striking freqeuntly resulting in failure to fire. Last night had a chat with our shotgun guru 12gauge after his pattings, tips & guidance dis assemble the gun to clean and lubricate the mechanism.

Sharing this cleaning experience with you so anyone having same issue can go through this with confidence.

Used bronox cleaner and lot of it, spraying on the whole mechanism generously and from the the front a swell so anything stuck in firing pin channel can be cleared. Left the piece in a plastic bowl for good 15-20 minutes also sprayed 2 times during that so loosened fouling can drip off in the bowl.
after 20 minutes sprayed it again and used a nylon brush (soft one) to give a mild & careful cleaning to the parts visible, nooks & corners but again VERY GENTLY. For cleaning the firing pin channel used a plastic straw (that comes with juices or cold drinks etc) to blow from the face after putting some cleaner on.

Kept the piece in standing position (face up) for about 10 minutes, blew it using all the strength of my (well abused) lungs & electric blow dryer, wiped everything clean with cloth, jolted the piece 2-3 times cleaned with cloth again and piece was ready to be lubricated.
Lubricated with gun lubricant, putting drops to each & every spring, moving part, hammer, hammer catch, firing pin spring that means lot of lubrication to the whole mechanism, used cloth to reach the narrow areas making sure nothing is left oil-less :)
Cleaned oil from the areas suppose to touch wood (of stock), assembled the gun and went to try it :) below are the photos after cleaning,

Checked the gun shooting total 15 cartridges (5 from over & 10 from under barrel) no problem of any sort :) but feeling sorry for the flying eagle got killed in the course of this testing & excitement :(

AoA Everybody

Good details Denovo Bhai and glad to see that everything worked out as expected. for those who wish to know "why a take down of O/U is Necessary every 1000 rounds or so". here it goes:

a detailed take down of an over and under shotgun (any double barrel for that matter) every 1000 rounds or so, is important/recommended to ensure following:

1. carbon/gunk/fouling cleanup and smooth functioning of everything inside the boxlock/sidelock
2. carbon when mixed with oil/grease turns into a lapping compound that can eats away metal. so a detail take down also ensures longevity
3. a fresh coat of oil inside all working parts to ensure smooth operation and resistance against rust.
4. oil/grease when mixed with carbon/gunk turns into a sticky lapping compounds that slows down or effects the movement of intricate parts that work together. such a clean up will ensure that "sticky firing pins" or "weak strikes" do not occur.
5. most of the doubling (both barrels firing at the same time) complaints can be removed with a detail cleanup of the action/boxlock/sidelock.

Bottom Line: a detail take down will ensure that your double barrel shotgun operates smoothly/flawlessly over extended period of ownership.

Very interesting. There should also be an exact same topic on Semi-Auto shotgun maintenance/tuning/cleaning with photos.

Denovo Sb, Nice Close/Detailed Photo Shoot. and also felt sorry for that poor eagle , very bad day for eagle to fly specially when Denovo is testing his skills.
